I bought one of their Pre-ban ARs back when there was a ban. I liked it and it never gave me a problem, but one day I found out that Pre-ban still mattered in the state of Connecticut, so I got my money back out of it. I think too much was made of the fact that they made cast receivers. When I bought mine, which was made before 1994, it was forged. Very few people, including myself, have even seen one in real life, let alone owned one. Olympic also provided all the information necessary to determine in the receiver in question was cast or forged.
However, budget features, such as a "long life non-chromed bore" or a mystery meat BCG just isn't going to get it done in 2017. I also remembered all the contact surfaces of my trigger group to be phosphated. It wouldn't surprise me to see several more AR companies fold without a buying panic in sight for the next 4 years. When many popular components in the AR world haven't been improved upon in decades, and big companies can flood the market with high quality parts, it's going to winnow the field.
